(Main)Domestic swimming pools - Water systems - Part 3: Water treatment - Requirements
General Information
- Abstract
This European Standard specifies requirements and test methods for equipment and means of pool water treatment utilized in domestic swimming pools.
This standard applies for swimming pools as defined in EN 16582-1 and will be read in conjunction with it.
This standard does not apply to:
- pools for public use covered by EN 15288-1;
- spas for domestic or public use;
- paddling pools according to EN 71-8;
- natural and nature like pools.
NOTE For filtration systems see prEN 16713-1 and for circulation systems see prEN 16713-2.
The purpose of this standard is furthermore to ensure a consistently high quality of pool water in terms of hygiene in order to prevent damage to human health, particularly as a result of pathogens. At the same time, account is also to be taken of the well-being of the bathers (e.g. by minimizing the side effects caused by disinfectants). To this end, requirements are specified for water quality and water treatment.

Overview
EN 16713-3:2016 - Domestic swimming pools - Water systems - Part 3: Water treatment - Requirements is a CEN standard that specifies requirements and test methods for pool water treatment equipment and procedures used in domestic swimming pools. Its objective is to ensure consistently high pool water quality and hygiene to protect human health (prevent pathogens) while minimizing adverse effects from disinfectants. The standard applies to pools defined in EN 16582-1 and explicitly excludes public pools (EN 15288-1), spas, paddling pools (EN 71-8) and natural/nature-like pools.
Key Topics
- Scope and safety: Obligations for manufacturers and installers to provide operating and chemical safety instructions for pool owners and operators.
- Fill water specifications: Recommendations for acceptable concentrations (e.g., iron ≤ 0.1 mg/l, copper ≤ 0.2 mg/l, manganese ≤ 0.05 mg/l, nitrates ≤ 50 mg/l) and guidance to test/treat non-mains water.
- Physical & chemical water quality parameters: Indicative values when using chlorine:
- pH: 6.8–7.6
- Free active chlorine (no cyanuric acid): 0.3–1.5 mg/l
- Free chlorine with cyanuric acid: 1.0–3.0 mg/l
- Cyanuric acid: max 100 mg/l
- Combined chlorine: max 0.5 mg/l
- Turbidity: max 1.5 FNU/NTU
- Redox potential: min 650 mV (Ag/AgCl reference)
- Disinfection: Requirements and recommended disinfectants (chlorine/bromine forms), dosing approaches (pumps, feeders, electrochlorination) and measurement (free chlorine, redox). Special notes on chlorinated isocyanurates, sodium/calcium hypochlorite, BCDMH and hypobromous acid.
- Flocculation/coagulation: Use of aluminium- or iron-based coagulants (EN 15031, EN 15797), guidance on when flocculation is required (e.g., removing Cryptosporidium) and cautions about staining/corrosion with iron-based products.
- Operational controls: Emphasis on filtration, pH adjustment, water balance, dilution, cleaning of pool, overflow channels and balance tanks, and routine monitoring/maintenance.
Applications
- Practical for pool manufacturers, designers, installers and service companies specifying equipment and control systems for domestic pools.
- Useful to pool owners/operators for safe chemical handling, routine testing and maintaining water quality.
- Relevant for chemical suppliers, installers of dosing and measurement equipment, and conformity testing bodies verifying compliance with domestic pool water-treatment requirements.
- Supports safe selection of disinfection strategy, dosing systems and maintenance regimes to meet hygienic and bather-comfort goals.
